Electric tyre pumps for vans

[DKL]

I need to find a good tyre pump for my folks to carry in the van when they are away. 2 key points it seems.
It's got to be man enough to cope with pressures upto 55psi as that is what they run at.
The leads need to be long enough to easily reach from the dash to the rear wheels.

I'm struggling a bit. I've found a ring one but its £70 and attaches straight to the battery. Not a huge issue but a bit more phaff.
Most of the others seem to top out at 50psi and have leads around 3m which on a 6m van is going to mean wending it through windows and doors to reach the back tyres.
What do people use?
Thanks

Thanks all, lots of options.
CC does it no work if its plugged in? I find some rechargable stuff does and some doesn't

CC thanks, Your edit was correct. Not quite so bad if it will work as long as there is power but still a pita if its supposed to be cordless.
